It seems your options are somewhat limited. While I had surgery to remove my AVM, I did have the option of radiation. I was discouraged from radiation due to the risk of another rupture before the AVM could be eliminated. Assuming that every treatment was spot-on.
After the surgery, I developed double-vision, which is a bit like being cross-eyed. To be honest, it's maddening. I have had three surgeries to correct, but all have failed. I am doing another round of vision therapy, but any progress is slow.
I wish I had learned more of radiation, and it's effectiveness. I would encourage you to meet with the best doctors available to you, and learn of the pros and cons of radiation.
Here is what my nerosurgeon told me. Radiation takes some two years to eliminate an AVM of my size. Mine was a 3. Additionally, during that time, I would face a risk of another bleed that would likely kill me. While a small chance, maybe four percent, it was believed to be too great. Also, the beam had to strike the AVM every time. If it struck adjacent to the AVM, the damage would be permanent, and may not manifest itself for years to come.
That's it in a nutshell. Good luck and be well.
